TRAMWAY TRUCK AND BAIL.

SPECIFICATION forming part of Letters Iatent No. 628,527, dated July 11,I899.

Application filed M rch 2 31 l 3 9 To aZZ whom it may concern:

Be it known that I, WILLIAM C. DAvIs, a citizen of the United States,residing at Denver, Colorado, have invented certain new and usefulImprovements in Tramway Trucks and Bails, of which the following is aspecification.

My invention relates to improvements in bucket-bails and trolleys forwire-rope tramways.

The object of the invention is to provide an improved form of frame madein one piece with separate bearings or bushings for the Wheels, and,further, to provide an improved form of hanger or bail for the bucket.

The invention is illustrated in the accompanying drawings, in WhichFigure 1 is a side elevation of the buckethanger and truck in positionupon a portion of a wireway. Fig. 2 is an end view of the same. Fig. 3is a plan view of the'truckframe on a larger scale. Fig. i is a sideele-' vation of the same. Fig. 5 is a part end view and part centraltransverse section of the frame. Figs. 6, 7, 8, and 9 are detail Viewsof the bail, illustrating more clearly the connection of the bail withthe truck-frame.

In .the drawings, the truck-frame is shown at A, and. it consists of twoparallel members A, connected by transverse webs Aland a tubular sleeveA all of which parts are cast integral. The end of these frame membersare provided with seats a, bored or otherwise formed in the frame, whichare adapted to receive separate bearin gs or bushings for thetruck-wheels, the bushings being clamped in place by suitable bolts andnuts.

The central portion of the frame is depressed to bring the sleeve Abelow the line of the bushings, and in this sleeve is located the pinwhich connects the hanger to the truck, as hereinafter described.

The hanger is shown at B, having a bucke 0 connected to its lower end inthe usual or any desired manner. This hanger consists of two members orbails B, diverging from the connecting-pin which connects them to thetruck-frame to points where they are secured to and held apart bya'grip-beam D, fromthe ends of which they depend vertically to thebucket.

It is extremely desirable to connect the bail $erial1l0. 710,232. (Nomodel.)

to the truck-frame without bolt-holes or welds in order to make a strongunion. For this purpose I provide the pin E, adapted to enter the sleeveor socket in the truck-frame, the forward end of the sleeve beingprovided with a head E, formed integral therewith. This head is open attop and bottom, forming an open socket, the end walls e of which divergefrom the center both upwardly and downwardly. The ends of the bails areprovided with angular portions 1), corresponding in shape to these walls6, the extreme upper ends of the bails being preferably overturned, asshown at 12 to rest upon the upper edges of the walls e. \Vedgcs e c areplaced between the ends of the bails above and below the center of thesocket, and these are drawn together by means of a bolt a passingthrough openings in the wedges, by means of which the ends of the bailsmay be securely wedged in position, thus dispensing with the necessityof rivet or bolt holes or any welding of the parts. I

The bails are held apart, as before stated, by a grip-beam D, which ispreferably made of cast-steel in the shape shown and is provided at itscenter with a seat for the ropegrip. The ends of the beam are preferablyangular to correspond to the angular bend in the bails, as shown at D,and are connected to the bails by suitable devices-such, for instance,as rivets d.

Having thus described my invention, what I claim is 1. Atruck-framehaving an elevated tramway comprising parallel members having depressedcentral portions, the webs and sleeve connecting the central portionsand cast integral therewith, seats in the ends of said members and thebearing-bushings detachably clamped in said seats, substantially asdescribed.

2. In combination, the truck-frame having the bearing socket or sleeve,a pin seated in said sleeve and havinga head provided with divergingwalls, bails for supporting the bucket or the like inserted between saidwalls and wedging means for clamping the ends of the bail in place,substantially as described.

3. In combination, the truck, the hollowheaded block having means forconnecting it with the truck, said block having walls diverging inopposite directions, bails for sup- In testimony whereof I aflix mysignature porting a bucket having ends bent to correin presence of twowitnesses. spend to send divergmg Walls, reversely-ar- WILLIAM C.
